Thanks Eric for your reply,. To answer to your question, I'm currently developing a kind of TermsComponent which is able to merge the terms of several fields and have the ability to reach a position in the list with a random access . To do that, I construct a merged list of terms from the Lucene Index for these fields. I need to rebuild this list each time the index has been modified. If an optimize changes the Lucene index data, so I have to detect it as I do for classical upates. Can I use the version number of the index to detect such modifications?
